This abstract mosaic of the Three Wise Men measures about 20x28. I made it in 1967 using pieces cut from construction paper and glued to a Masonite board that had been painted with white gesso. The pieces were glued on so that a little of the white showed between each piece to look like grout.
It’s about 50 years old and the colors are still fairly bright because I only hang on the wall for a couple of weeks in December. Some years I don’t display it at all because construction paper fades when exposed to light.
